The University of Southern California is a private, not-for-profit, nonsectarian, research university founded in 1880 with its main campus in the city area of Los Angeles, California. As California's oldest private research university, USC has historically educated a large number of the region's business leaders and professionals. In recent decades, the university has also leveraged its location in Los Angeles to establish relationships with research and cultural institutions throughout Asia and the Pacific Rim. In 2011, USC was named among the Top 10 Dream Colleges in the nation. It holds a vast array of trademarks and wordmarks to the term "USC."For the 2012-2013 academic year, there were 18,316 students enrolled in four-year undergraduate programs. USC is also home to 21,642 graduate and professional students in a number of different programs, including business, law, social work, and medicine. The university has a "very high" level of research activity and received $560.9 million in sponsored research from 2009 to 2010. USC sponsors a variety of intercollegiate sports and competes in the National Collegiate Athletic Association as a member of the Pacific-12 Conference. Members of the sports teams, the Trojans, have won 100 NCAA team championships, ranking them third in the nation, and 378 NCAA individual championships, ranking them second in the nation. Trojan athletes have won 287 medals at the Olympic games , more than any other university in the world. If USC were a country, it would rank 12th in most Olympic gold medals. Wikipedia.

Disclosed herein are stable organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material having a sufficiently high glass transition temperature, e.g., higher than the temperature or temperature range at which the device typically operates, higher than a highest operating temperature of the device, higher than a threshold temperature value, etc. and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).

This disclosure relates to the field of Optical Coherence Tomography (OCT). This disclosure particularly relates to methods and systems for providing larger field of view OCT images. This disclosure also particularly relates to methods and systems for OCT angiography. These systems may allow OCT scanning for an extended duration and generation of large field OCT images suitable for the OCT angiography.

This disclosure also particularly relates to methods and systems for OCT angiography. This disclosure further relates to systems for health characterization of an eye by OCT angiography. This OCT angiography system may determine a feature of a vasculature within an eye tissue and thereby identify a vascular anomaly and a spatial location of the vascular anomaly within the eye tissue.

A module may be provided with at least one opening, the opening being an endpoint of a microfluidic channel that passes through at least part of the module. A set of multiple such modules may be arranged into an arrangement of modules, which may be coupled together using one or more coupling mechanisms included on each module. The arrangement of modules may fit within a regular polyhedral grid, and each module within the arrangement of modules may have a form suitable for arrangement of the modules within the regular polyhedral grid. Fluid may then flow through at least a subset of the arrangement of modules via the microfluidic channel of each module of the subset of the arrangement of modules. Some modules may include sensors, actuators, or inner microfluidic channel surface coatings. The arrangement of modules may form a microfluidic circuit that can perform a microfluidic circuit function.

The neurovascular unit (NVU) comprises brain endothelial cells, pericytes or vascular smooth muscle cells, glia and neurons. The NVU controls blood-brain barrier (BBB) permeability and cerebral blood flow, and maintains the chemical composition of the neuronal 'milieu', which is required for proper functioning of neuronal circuits. Recent evidence indicates that BBB dysfunction is associated with the accumulation of several vasculotoxic and neurotoxic molecules within brain parenchyma, a reduction in cerebral blood flow, and hypoxia. Together, these vascular-derived insults might initiate and/or contribute to neuronal degeneration. This article examines mechanisms of BBB dysfunction in neurodegenerative disorders, notably Alzheimer's disease, and highlights therapeutic opportunities relating to these neurovascular deficits. © 2011 Macmillan Publishers Limited.

WNT-β-catenin signalling is involved in a multitude of developmental processes and the maintenance of adult tissue homeostasis by regulating cell proliferation, differentiation, migration, genetic stability and apoptosis, as well as by maintaining adult stem cells in a pluripotent state. Not surprisingly, aberrant regulation of this pathway is therefore associated with a variety of diseases, including cancer, fibrosis and neurodegeneration. Despite this knowledge, therapeutic agents specifically targeting the WNT pathway have only recently entered clinical trials and none has yet been approved. This Review examines the problems and potential solutions to this vexing situation and attempts to bring them into perspective. © 2014 Macmillan Publishers Limited.

Double-strand DNA breaks are common events in eukaryotic cells, and there are two major pathways for repairing them: homologous recombination (HR) and nonhomologous DNA end joining (NHEJ). The various causes of double-strand breaks (DSBs) result in a diverse chemistry of DNA ends that must be repaired. Across NHEJ evolution, the enzymes of the NHEJ pathway exhibit a remarkable degree of structural tolerance in the range of DNA end substrate configurations upon which they can act. In vertebrate cells, the nuclease, DNA polymerases, and ligase of NHEJ are the most mechanistically flexible and multifunctional enzymes in each of their classes. Unlike repair pathways for more defined lesions, NHEJ repair enzymes act iteratively, act in any order, and can function independently of one another at each of the two DNA ends being joined. NHEJ is critical not only for the repair of pathologic DSBs as in chromosomal translocations, but also for the repair of physiologic DSBs created during variable (diversity) joining [V(D)J] recombination and class switch recombination (CSR). Therefore, patients lacking normal NHEJ are not only sensitive to ionizing radiation (IR), but also severely immunodeficient. © 2010 by Annual Reviews. All rights reserved.

DNA methylation is frequently described as a 'silencing' epigenetic mark, and indeed this function of 5-methylcytosine was originally proposed in the 1970s. Now, thanks to improved genome-scale mapping of methylation, we can evaluate DNA methylation in different genomic contexts: transcriptional start sites with or without CpG islands, in gene bodies, at regulatory elements and at repeat sequences. The emerging picture is that the function of DNA methylation seems to vary with context, and the relationship between DNA methylation and transcription is more nuanced than we realized at first. Improving our understanding of the functions of DNA methylation is necessary for interpreting changes in this mark that are observed in diseases such as cancer. © 2012 Macmillan Publishers Limited.

The glucose-regulated proteins (GRPs) are stress-inducible chaperones that mostly reside in the endoplasmic reticulum or the mitochondria. Recent advances show that the GRPs have functions that are distinct from those of the related heat shock proteins, and they can be actively translocated to other cellular locations and assume novel functions that control signalling, proliferation, invasion, apoptosis, inflammation and immunity. Mouse models further identified their specific roles in development, tumorigenesis, metastasis and angiogenesis. This Review describes their discovery and regulation, as well as their biological functions in cancer. Promising agents that use or target the GRPs are being developed, and their efficacy as anticancer therapeutics is also discussed. © 2014 Macmillan Publishers Limited. All rights reserved.
